hello I would like to install a funtoo as a qemu kvm guest ( boring by debian never up to date and arch is completely weird and tricky in my opinion) I would like to know the special things to do to achieve this for example I use the host-cpu option so I suppose I need the version of tar.xz matches with my hardware cpu ?? do i need a special option during the kernel compilation ?? so if you have suggestion about do this clean you are welcome ps :: I do a passthrough for vga I think I need to do the kernel task for my vga controler normaly ?

thank you Oleg. I will try today, but I don't use hardened kernel, I use current piledriver stable hope it will not be disturbing
Have fun !! [edit]
ok lol in waiting to a fix thank you !! i juste post my issue on bug.funtoo as comment i don't know if it's the good process say me if i did something wrong i'm not use to this (post on forums , bug reports)

Hello cardinal, I'm not sure to understand; do you purpose to file a bug report for my case ? if i understand well, my answer is I don't know !! how long is in general the time for the dev to make a patch like that ? and i'm not sure it 's really important i just need the catalyst for virtualgl. I try to make it work with an app server on xen or kvm and the graphics with virtualgl on the dom0 I had yet make it work with a xen serv and an ssh connexion with a virtualgl machine and another ssh connection with a thin client (little tricky i know :D ) i'd like to know if its possible to do work 2 or 3 minecraft client with one hd7970 i don't need, i think the last kernel for that
have fun !

Hello I'm new here, i experiment a little bit on funtoo and I admit the world of custom kernel is new for me My problem is during the install of catalyst driver 14-20 from the amd site on a custom 4.5.2 kernel. I had build the header whith make headers_install and in first I had an issue that said version.h not found so I had copy the file in /lib/modules/4.5.2/build/include/linux/version.h but after this I had another issue :
Supported adapter detected.
Check if system has the tools required for installation.
Uninstalling any previously installed drivers.

furthermore I had read somthing I think about it on fedora (https://bluehatrecord.wordpress.com/2015/09/17/installing-the-proprietary-amd-catalyst-15-9-fglrx-15-201-driver-on-fedora-22-with-linux-kernel-4-1-6/)but the english is not my language and all this stuff are news for me (kernel, funtoo, and graphical driver hack )
can someone help me ? ps: i'm not use to post on forums and with html sorry if they are no html balise.
